The ictus among young people are on the rise. A genetic meta-analysis has determined that there are blood groups with a higher risk of suffering a strokeif you are under 60 years old.
the stroke or cerebral stroke It occurs when blood stops reaching the brain because a vein has ruptured or become clogged. The severity depends on how long the brain spends without blood supply.
In Spain they are produced between 110,000 to 120,000 strokes each year, and 50% cause death or disabling sequelae, according to data from the Spanish Society of Neurology. Now neurologists are concerned about how strokes are increasing alarmingly among young people.
In recent years, strokes among people aged 20 to 60 have increased from 25 to 31%. With the associated tragedy that if a 30- or 40-year-old suffers serious sequelae after a stroke, such as partial paralysis or other problems, they will have to live with it for decades, in addition to following a rehabilitation.
As our colleague Cristina Fernández explains in Business Insider, until now there were few studies of causes of stroke in young people. That is why Dr. Steven J. Kittner, professor of Neurology at UMSOM and neurologist at the University of Maryland Medical Center, and his team have carried out a mega-study that has been very revealing.
Blood groups and stroke
Kittner and his team conducted a meta-analysis of 48 studies on genetics and stroke. ischemic which included 17,000 patients with this blood flow condition, and nearly 600,000 healthy controls who had never experienced one.
The study focused on genetic variants associated with strokesand discovered a relationship between genes associated with blood groups and stroke in people under 60 years of age.
The study concludes that Those under 60 years of age with type A blood group are 16% more likely to suffer a stroke than the other blood groups. Instead those who are type 0, have 12% less chance of suffering uno cerebral infarction.
The reason seems to be that type A blood favors the appearance of blood clotsAccording to Dr. Kittner: “it likely has something to do with blood clotting factors, such as platelets and the cells that line blood vessels, as well as other circulating proteins, all of which play a role in the development of blood clots.”
Although the percentages of suffer a stroke according to blood group are there, the report concludes that should not be a cause for concern, because that percentage is applied to the punctual risk. That is, if due to your health or genes you have a 2% chance of suffering an ischemic stroke, and you are type A, that extra 16% is applied to 2%, increasing it to 2.3%, which is not worrying.
